🇹🇭 Thailand Network Coverage
5G in Bangkok + Chiang Mai + Phuket + Pattaya + Koh Samui airport; 4G LTE across all 77 provinces + all inhabited islands · eSIM plans connect to local networks on arrival
eSIM Tips for Thailand
BKK + DMK airport SIM kiosks queue 20-45 min at peak (post-midnight arrivals from EU + AU). eSIM activated in-flight skips it.
AIS has the widest 5G rollout (Bangkok CBD, Chiang Mai city, all Phuket beaches, Koh Samui Chaweng). True Move H matches on Bangkok + Chiang Mai + Pattaya.
DTAC merged with True in 2023 — legacy DTAC plans now run on True Move H network. Same coverage, unified backbone.
Correct choice for Indochina loops.
Coverage on islands: Koh Samui (full 4G), Koh Phangan (full), Koh Tao (patchy at Sairee, full at Mae Haad), Phi Phi (Ton Sai + Loh Dalum full 4G, Phi Phi Le boat trips no signal), Similans + Surin (no signal, park regulations).
Grab + LINE MAN (food delivery) work with international phone numbers for booking. Payment: cash or international Visa/Mastercard — TrueMoney + PromptPay require Thai bank + ID.

Thailand eSIM FAQ
How much does an eSIM for Thailand cost?
Airalo's cheapest Thailand plan was €4.00 for 1 GB over 3 days, and €7.50 for 5 GB over 30 days, as listed on airalo.com on 8 October 2026. Prices are shown in EUR; Airalo may show your local currency.
How long do Thailand eSIM plans last?
Airalo sells Thailand plans valid for 3, 5, 7, 10, 15, 30 days (airalo.com, 8 October 2026). The validity usually starts when the eSIM first connects to a network there.
Which eSIM works best in Thailand in 2026?
Best coverage on islands: any AIS-backed plan (widest coverage in Krabi + Koh Samui + Koh Phangan).
Does eSIM work in Phuket, Koh Samui, Koh Phangan, Krabi, and the islands?
Yes — full 4G on AIS + True Move across all major islands: Phuket (Patong + Kata + Karon + Nai Harn + Rawai + Kamala), Koh Samui (Chaweng + Lamai + Bophut + Fisherman's Village), Koh Phangan (Haad Rin + Baan Tai + Chaloklum), Koh Tao (Mae Haad + Sairee), Phi Phi Don, Ao Nang, Railay. No signal at all on Similan + Surin Islands (national park regulations). Boat crossings: usually signal for the first 30 min out from mainland, then variable.
Can I use my eSIM from Bangkok to Bali or Singapore on the same trip?
No re-activation at borders, no data interruptions. Ideal for the classic BKK → Chiang Mai → Luang Prabang → Siem Reap → Ho Chi Minh → Bali circuit.
Does eSIM work on the Bangkok BTS + MRT + Airport Rail Link?
Yes — full 4G on AIS + True Move across the entire BTS Sukhumvit + Silom lines, MRT Blue + Purple lines, and Airport Rail Link (SA City Line + Express). Underground stations at Silom + Sukhumvit + Chatuchak: full signal via installed repeaters. Also full signal at Suvarnabhumi (BKK) baggage claim + Don Mueang (DMK) departure gates.
Thailand eSIM for digital nomads (30+ day stay)?
Digital nomad hubs (Chiang Mai Nimman, Bangkok Ekkamai, Koh Phangan Sri Thanu) all have fibre WiFi cafes — eSIM is your backup.
